Photojournalist Jo Hathaway, overworked and under stress, begins to have nightmares about her mother, who disappeared years earlier. At the same time, she starts receiving peculiar private photographs of herself via e-mail from an unknown "friend." Jo retreats to her childhood island home -- Sanctuary Inn -- for an overdue visit with her family, including father Sam, Aunt Kate and brother Brian. Soon after she arrives, Jo bumps into Nathan, a handsome acquaintance from her past. Although Jo tries to avoid a romance with Nathan, she finds herself unable to ignore her affection for him. But romance is soon interrupted by a series of frightening incidents. Jo realizes that by returning to Sanctuary, instead of escaping her problems, she has walked right into them.
